BACKGROUND Remote ischaemic pre-conditioning and cardiac ischaemic post-conditioning provide myocardial protection in cardiac surgery. However, these two endogenous strategies have not been directly compared in a clinical setting. The purpose of this study was to compare the efficacy of remote ischaemic pre-conditioning and post-conditioning in providing(More)
OBJECTIVE Ischemic postconditioning (POC) by brief episodes of ischemia performed just at the time of reperfusion can reduce infarct size in animal models and clinical settings of percutaneous coronary intervention. However, the clinical applicability of postconditioning in cardiac surgery remains to be determined. We investigated the effect of(More)
BACKGROUND Postconditioning by brief episodes of ischaemia performed just at the time of reperfusion have been shown to reduce the size of infarcts in animal models, and in the clinical setting of percutaneous cardiac intervention. The clinical applicability of postconditioning in cardiac surgery remains to be determined. We investigated the effect of(More)
The postoperative course of cyanotic patients is generally more complicated than in acyanotic patients. The ischemic postconditioning provides protection from myocardial injury. We conducted a randomized trial to evaluate the clinical benefits of postconditioning in patients undergoing repair of tetralogy of Fallot. Ninety-nine patients with tetralogy of(More)
In this paper, we present a distributed fault detection algorithm based on k-means clustering for WSN. The nodes within a cluster are divided into three sub-clustering according to their measurements' similarity. We conclude the sensor nodes' working state from the N recent states of sub-clustering, so as to detect, locate, and get rid of the fault nodes.(More)
Fault detection of wireless sensor networks has been studied intensively in recent years under the assumption that manager nodes are default probe stations. However, some additional fault detection tasks will make so busy the manager node to be failed more quickly. Moreover, at the first beginning period most sensor networks are working normally without any(More)
We previously found that remote ischemic perconditioning (RIPerc) was effective in attenuating myocardial injury during cardiac surgery. Given that microRNAs (miRs) act as an important player in ischemic/reperfusion (I/R) injury and apoptosis, this study aimed to investigate whether RIPerc reduces apoptosis in atrial myocardium and which apoptosis-related(More)
Fault detection for wireless sensor networks (WSNs) has been studied intensively in recent years. Most existing works statically choose the manager nodes as probe stations and probe the network at a fixed frequency. This straightforward solution leads however to several deficiencies. Firstly, by only assigning the fault detection task to the manager node(More)
BACKGROUND Remote ischemic perconditioning (RIPerc) is a new alternative of remote ischemic conditioning and has not been well studied. RIPerc attenuates myocardial injury when applied during cardiac surgery. However, its protective effects on other organs remain unknown.
